Abstract:

Reducing ongoing risks to survival and reproduction and enhancing the recovery of endangered or threatened species requires an understanding of basic chemical and physical habitat attributes. Previous studies have concluded that water quality has not been the primary habitat attribute linked to the endangerment of Rio Grande silvery minnow (Hybognathus amarus; silvery minnow) in the Middle Rio Grande (MRG) of New Mexico (Marcus et al. 2005, 2010; New Mexico Environment Department 2009). As such, this assessment provides additional focus on physical habitat features (specifically, key ecohydrological constraints) that appear to place silvery minnows at continued risk for population decline in the MRG.
